SHEET-METAL CASING FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 364,417, dated June 7,1887.

Application filed Eeptcmber 1 7, 1886. Serial No. 213,78Bi' (Modem ToaZZ whom it may concern.-

Be it known that I, JULIUS JAEGER, of Rutherford, Bergen county, NewJersey, have invented certain new and useful Improvements in Sheet-MetalCasings for Bottles, 850., of which the following is a specification.

The object of my invention is to provide a new and improved sheet-metalcasing for packing bottles or like fragile articles for transportation,and for containing and holding liquids, or finely powdered or viscoussubstances, which casing is strong, can resist very powerful compressionstrains, can be closed hermetigally, and opened and closed easily andrap i ly.

The invention consists in a sheet-metal cas ing having circumferentialcorrugations closed by a screwcap, and that part of the casing adjacentto the opening provided with external beads, all as will be fully setforth hereinafter, and finally pointed out in the claim.

In the accompanying drawings, Figure 1 is a longitudinal sectional viewof my improved sheet-metal casing forbottles, &e., on the line mm, Fig.2. Fig. 2 is a sectional plan view ot the same on the line 3 Fig. 1.Fig. 3 is a erossseetional view of the double-lock joint before it iscompressed. Fig. 4 is across-sectional view of the same compressed.

Similar letters of reference indicate corre sponding parts.

The sheet-metal case A is formed of two cylindrical or like sections, AA drawn from sheet metal without seams and united by a double-lockjoint, a, the several layers of which are pressed firmly together toform a solid exterior circumferential head on the cas 111g. numeroushollow circumferential ribs, 0, which are formed by means of alathe, orin any other suitable manner. The bottom of the casing is madeintegral with the bottom section, A. The section A is provided at itsupper end with a screw-thread, D, which is formed directly adjacent tothe uppermost head or rib, C, an inwardly-projecting flange, F, beingformed on the upper end of the screw-thread D. t A screw-cap, E, whichcan be screwed on the thread D, is provided along the edge of the closedend with a hollow bead, N, into The casing A is also provided withwhicha packing ring, G, is placed, which, when the cap'is screwed on thecasing, is pressed upon the flange F and forms a herlnetieallysealedjoint. When the cap is screwed on the casing, the bead N and theuppermost head, 0, of the casing projectlaterally a short distancefarther than the screwthread, and thus form guards for the same, therebyprotecting the screw-thread from injury while handling the casing, orwhen the casing is accidentally subjected to blows or heavy compressionstrains.

The article to be protected is placed in the casing,ai1d sawdust or anyother suitable packing .or protecting material or substance is packedbetween said article and the sides of the casing. The cap is thenscrewed on. The circumferential ribs 0 strengthen and stiffen thecasing, so that the same can resist a very great compression strain,either laterally or longitudinally. The solid rib a, at or near thecenter of the casing, strengthens or stiffens 3 the casing at itsweakest point, said solid Ilb having greater resisting power againstcompression strains than the hollow ribs 0.

Smaller casings can be made of a single piece and the solid rib omitted.The casing might be provided with longitudinal ribs; but I prefer thecircumferential ribs. The screw-cap and the closed end of the casing maybe provided with circumferential ribs.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- The combination, with a sheet metal casing having ascrew-th read at one end, and a hollow bead directly below saidscrew-thread, which bead projects farther than the threads, said casingalso having circumferential corrugations on the space between the beadand the opposite closed end of the casing, of a screwcap which can bescrewed on the thread at the open end of the casing, which cap has abead,

M, substantially as shown and described.
